mneu problem

page.winW=function()
{ with (this) return Math.max(minW, MS?win.document[db].clientWidth:win.innerWidth) };
page.winH=function()
{ with (this) return Math.max(minH, MS?win.document[db].clientHeight:win.innerHeight) };
page.scrollX=function()
{ with (this) return MS?win.document[db].scrollLeft:win.pageXOffset };
page.scrollY=function()
{ with (this) return MS?win.document[db].scrollTop:win.pageYOffset };

function repositionMenus(mN) { with (this)
{
var menu = this.menus[mN].lyr;

// Showing before measuring corrects MSIE bug.
menu.sty.display = ‘block’;
// Reset to and/or store original margins.
if (!menu._jsm_origML) menu._jsm_origML = menu.ref.currentStyle ?
menu.ref.currentStyle.marginLeft : (menu.sty.marginLeft || ‘auto’);
if (!menu._jsm_origMT) menu._jsm_origMT = menu.ref.currentStyle ?
menu.ref.currentStyle.marginTop : (menu.sty.marginTop || ‘auto’);
menu.sty.marginLeft = menu._jsm_origML;
menu.sty.marginTop = menu._jsm_origMT;

// Calculate absolute position within document.
var menuX = 0, menuY = 0,
menuW = menu.ref.offsetWidth, menuH = menu.ref.offsetHeight,
vpL = page.scrollX(), vpR = vpL + page.winW() – 16,
vpT = page.scrollY(), vpB = vpT + page.winH() – 16;
var mp = page.elmPos(menu.ref);

// Compare position to viewport, reposition accordingly.
var mgL = 0, mgT = 0;

if (mp.x + menuW > vpR)
{
// mgL = -menuW ;
if(this.menus[mN].par.lyr.ref.offsetWidth > menuW);
{
mgL = – menuW-27;
}
}
if (mp.x + mgL < vpL) mgL = vpL – mp.x;
if (mp.y + menuH > vp? mgT = vpB – mp.y – menuH ;
if (mp.y + mgT < vpT) mgT = vpT – mp.y;

if (mgL) menu.sty.marginLeft = mgL + ‘px’;
if (mgT) menu.sty.marginTop = mgT + ‘px’;
}};

// Set this to process menu show events for a given object.
//addEvent(listMenu, ‘show’, repositionMenus, true);
here is the javascript function for the menu
